Throughout my career, I've owned and managed small businesses. In a small business everyone must wear many hats, and I generally wore dozens.
Because I always wanted my companies to have the latest technical edge, one of the hats I often wore was the 'tech guy'. Over the years I have written programs, developed applications, installed networks, recovered data, replaced hardware, put out RFP's for infrastructure software, and even written a letter or two in WordPerfect on a mono-chrome monitor (I resisted Word for years).
As the owner/operator of companies that generated as much as $14,000,000 in annual revenues, I'm well versed in detailed business analyses and reporting.
